If it's greater than three months and it's there all the time while you're awake, that's chronic throat-clearing. Two of the most common causes of frequent throat clearing are laryngopharyngeal reflux, or LPR, and seasonal allergies, explains Song. advertisement. Reflux from the stomach, which may or may not be acidic, comes up through the esophagus and into the back of the throat, where it can irritate the voice box. People with LPR may also have post-nasal drip, an excess of throat mucus, or the feeling like something is stuck in the throat, but nothing is there.
People wrongly presume they donât have acid reflux if they donât have heartburn â but actually throat-clearing can be the main symptom. The acid causes irritation in the oesophagus and this irritation triggers the production of mucus. Throat clearing is a reflex response to clear this mucus.
